Capacity calculation method of energy storage system based on flexibility index of photovoltaic, energy storage, direct current and flexibility (PEDF) system in buildings
摘要：
建筑光储直柔系统是帮助建筑领域实现碳达峰、碳中和的重要技术手段,其中系统的储能形式较多采用储能电池。本文基于标准的柔性指标要求,以深圳某实际项目为例,介绍了一种项目储能容量的计算方法。该项目直流负荷总功率为762.65 kW,计算得所需储能容量为470 kW·h。在柔性调节过程中充电桩系统对调节量的贡献最大,约为56.09%;照明系统对调节量的贡献最小,仅为5.13%。
Abstract：
The photovoltaic, energy storage, direct current and flexibility (PEDF) system in buildings is an important technical means to help the building field achieve carbon peaking and carbon neutrality, in which energy storage forms are mostly energy storage batteries. Based on the flexible index requirements of the standards, a calculation method of battery capacity is presented and a practical project in Shenzhen is chosen as a case study in this paper. The total direct current load power of the project is 762.65 kW, and the required energy storage capacity is calculated to be 470 kWh. In the process of flexible adjustment, the charging pile system contributes the most, about 56.09%, while the lighting system contributes the least, only 5.13%.
